Description
Technical field
The utility model relates to linear rail attachment technique field, especially a kind of straight-line ball guide pin bushing that is widely used in the machinery sliding positions such as lathe, grinding machine.
Background technique
Linear rail is widely used in various industry equipments and precision type instrument, and as vitals wherein, precision and the wear-resisting property of straight-line ball guide pin bushing are all greatly improved.But traditional straight-line ball guide sleeve structure is complicated, install and keep in repair loaded down with trivial details, precision and stationary performance are all not high, and wear-resisting property is poor, greasy property is also bad, need often maintenance or change, after service time is long, wearing and tearing very large, and can generate heat, can shorten working life, reduced manufacturing efficiency, improved cost of production.Therefore, need a kind of new technological scheme to address the above problem.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, the straight-line ball guide pin bushing of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of straight-line ball guide pin bushing, comprise rotating shaft and be set in the bearing housing outside rotating shaft, bearing housing comprises retainer and bearing housing shell, between retainer and bearing housing shell, be provided with ball, described bearing housing two ends are provided with stop ring, bearing housing shell is provided with pin-and-hole outward, inserts pin retainer and bearing housing shell are coupled together in pin-and-hole; In described rotating shaft, offer the rolling raceway groove of many circular arcs, do not need to prevent the mechanism of bearing housing rotation, its load rating increases substantially.Can realize the compactness of guide portion structure, cost degradation and long lifetime.
Further, described bearing housing shell is provided with the oil hole that injects lubricant oil.
Further, in described rotating shaft, offer four rolling raceway grooves.
Further, described retainer is resin retainer.
Further, described retainer is stainless steel holder.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, the rolling raceway groove that offers many circular arcs in rotating shaft can improve load rating, be provided with the greasy property that the oil hole that can inject lubricant oil can improve straight-line ball guide pin bushing, improve the wear-resisting property of straight-line ball guide pin bushing, increase the service life, bearing housing two ends are provided with stop ring, have dustproof advantage.
